My invention .relates to improvementsin combination disk Wheels, as. carrying ivheels for -motcr ehicleisg 'iand the object of my pneumatic tire.

improw ement is to furnish a sectional Wheel of this class Whichcombinesbut two struc-.-. tural parts toprovi'dea discoidalcenter Web and a separable rim to- :detachablyl hold a i W' liile the centralweb of the Wheel as -in- .cluding parts of'the sectionsland; 2 may be I flat; yet Ifprefer that the overlapped parts thereof be annularly-concaved out ardly' as illustratedinFig. 3, and that the section 1 may be shaped With a relatively Jlargec'entraI dishing inwardly at 6..t'obe Another ob] set is? to separable terlocking'fastening devices with which to secure said sectional parts together.

= Witlrthe "foregoing and other objects it vi w which Will -appear 'a'sthe description proceeds,"theqinvention resides in the com- I bination'an'd arrangement ofparts and'in the details 'ofconstruction lhereinafter, de

- Myi disk wheelis; believed' tocomprise" fewer parts than other wheels of that class; and has the advantage that'ithas -'-com bination disk'land sectional rim'so constructed and assembled that a -tire may be mounted or 'demounted thereon Without the, necessity "It is further thought that the Wheel is strengthened to 'an unusual degree by the assembling of parts of the diskfand rim in juxtaposition so as to reinforce the structure in" resisting both Vertical strains (and torsion such as are commonly experienced While the v Wheel is heavily l -loaded rotating over rough surfaces at high-speed, and violently thrust the vehicle is being changed.
